Hi Hernán, this could mean two clients had different notions of what class 378 is. I would use the FileTraverser to take a count of your 378's; see first if you have consistency.
Do you have any suspicions about the cause of the problem?
some questions:
- What version of Magma?
- Is DateQualifier a kind-of Set?
- Did you extend (subclass) any class included in the MagmaSession protocol?

Option 2: What matters is that STBUser buffers in the repository all point consistently to the correct class version. Write a script using MagmaFileTraverser to interrogate all of the Fixed buffers ("type = 3") where classId=126, check that their versions all are correct and consistent with their number of instVars of the Buffer (#objectInstSize).
I have a similar problem ( 'DateQualifier cannot have variable sized instances' ) but in my case there's only one version of DateQualifier, ( i.e. aMagmaClassIdManager definitionForClassId: 378 version: 2 fails because non-existent index). Here objectInstSize = 2 and sourceDefinition namedInstSize = 3, resulting in indexedSize = -1 and performing the #basicNew:
#namedInstSize is correct, the DateQualifier's superclass has 3 instance variables, the output of Jerry's first script would be:
Index: 1 Version: 1 ivar count: 3
So I wrote the script you suggested:
( MagmaFileTraverser for: 'Magma' ) open anchorGraphDo: [ : buffer | ( buffer classId = 378 and: [ buffer class = MaFixedObjectBuffer ] ) ifTrue: [ buffer objectInstSize inspect ] ].
but still fails with the same error. My problem is that I cannot open the repository to commit any corrections because of this error.
